Background: Arirang is a UNESCO Intangible Cultural Heritage and intangible cultural property No. 129. However, research on the origin of Arirang in Seoul is still narrowly conducted, and it is necessary to investigate it academically. Purpose: This study is to clarify the research on the origin of traditional Arirang in Seoul area on a theoretical basis. Methods: I searched various documents to find the source of Arirang in Seoul. Results: The record of 'Arirang' was first confirmed as 'Arirang Taryeong(song)' in 'Hanyang-ga' in Maecheonyarok (Maecheon's history) by Hwang (1894). After that, Hulbert (1896) published the first modern sheet music and lyrics of <A-ra-rung> on music paper. In addition, Lee Sang Jun (1914) edited <Old Korean Folk Songbook, First volume> and recorded the lyrics and score titled 'Arirang Taryeong' on page 25 and the long Arirang Taryeong. Conclusions: Literally, the origin of 'Arirang in Seoul' is 'Arirang Taryeong' first recorded in 'Hanyang-ga' of Maecheonyarok. Arirang song, which originated in Hanyang, can be called Seoul Arirang. It is suggested that Seoul Arirang has a very high value as a protected cultural heritage of Seoul because of its historical and cultural characteristics.

Purpose: Arirang, the most beautiful song in the world, has been meeting with natural healing to increase synergy. Arirang and nature healing have pioneered the field of Arirang music healing by crossing different boundaries. Methods: Arirang Gymnastics was used. Results: New Arirang Gymnastics is part of the healing of Arirang music, which consists of six movements. Starting with warm-up exercises in time for Seoul Arirang, the patient will apply pressure to the pit of the pit of the stomach, the head of the stomach, and the non-surface field. To match Haeju Arirang, massage the right side of abdomen, left side underbed, top (stomach), and lower bladder. Tap the Danjeon, the bladder, the heart, and the lungs in accordance with Millyang Ariryang. Stretching both arms and shoulders in line with Arirang in Gangwon Province, the two sides meet behind each other. Rotate the shoulders and wrists in line with the progress of the arm. Conclusions: Aerobic exercise that is tailored to new Arirang and their gymnastics are useful for health and healing of the body and mind.

The purpose of this study is to raise the drinking rate of Arisu, the tap water in Seoul, and to propose new solution for continuous water quality management and raising awareness. The research scope was limited to point-of-use water treatment system, and based on the this contents I proceed this study how this will help to increase direct drinking rate of Arisu. Through research, Korea has provided users with the ability to filter contaminated tap water simply as water to be rinsed through water purification. Therefore, it was predicted that it would be difficult to improve tap water as drinking water. With this study, I expect that the strength of point-of-use system and the reliability of tap water quality will be raised and hope various product will be developed to improve the perception as drinking water and I also expect that this can be applied to whole country even further in the scope of Seoul city.

영상 레이다(Synthetic Aperture Radar: SAR)는 기상조건이나 주야에 관계없이 전천후로 광범위한 지역의 영상을 고해상도로 얻을 수 있는 능동형 전자파 레이다 센서이다. 최근 세계적으로 위성 SAR는 2010년을 기점으로 최근 3~4년 사이에 유사이래 가장 많은 13개 이상의 저궤도 소형 SAR 위성들을 발사함에 따라 비로소 "저궤도 위성 SAR 전성기"로 진입하게 되었다. 우리나라에서도 아리랑위성 5호(KOMPSAT-5)에 SAR를 탑재하는 최초의 레이다 위성을 올해 2011년에 발사할 계획을 가지고 있으나 아직 발사가 지연되고 있다. 본 기고에서는 2011년 9월 27~30일 서울에서 개최된 국제 영상 레이다 학술 대회 APSAR 2011(Asia-Pacific Conference on Synthetic Aperture Radar)의 성공을 기념하여 마련된 SAR 기술 특집호에 최신 위성 SAR 개발 동향을 중심으로 기술 발전 추세와 전망에 대하여 소개한다.

Urban expansion results in raising the temperature in the city, which can cause social, economic and physical damage. In order to prevent the urban heat island and reduce the urban land surface temperature, it is important to quantify the cooling effect of the features of the urban space. Therefore, in order to understand the relationship between each object of land cover and the land surface temperature in Seoul, the land cover map was classified into 6 classes. And the correlation and multiple regression analysis between land surface temperature and the area of objects, perimeter/area, and normalized difference vegetation index was analyzed. As a result of the analysis, the normalized difference vegetation index showed a high correlation with the land surface temperature. Also, in multiple regression analysis, the normalized difference vegetation index exerted a higher influence on the land surface temperature prediction than other coefficients. However, the explanatory power of the derived models as a result of multiple regression analysis was low. In the future, if continuous monitoring is performed using high-resolution MIR Image from KOMPSAT-3A, it will be possible to improve the explanatory power of the model. By utilizing the relationship between such various land cover types considering vegetation vitality of green areas with that of land surface temperature within urban spaces for urban planning, it is expected to contribute in reducing the land surface temperature in urban spaces.

The tap water plays a critical role in our daily life by providing clean water for drinking as well as for residential use. Its importance, however, is often hidden and criticized in mass media because drinking the unprocessed tap water as a primary source of drinking water is very low comparing to other countries. This is because survey tool in Korea is often different from those in other countries so their results on the tap water cannot be directly compared without analysis on survey questionnaire. Therefore, we examplified cases showing the difference of questions of each country and discussed the reason why results of tap water intake should not be compared without analysis on the questions. Also, distrust on Arisu without rational reason is known as the first reason of distrust on the tap water. However, it was not the ultimate reason of distrust on the tap water. To verify, we designed survey questions in a tricky way that the same question was asked twice with different choices in the survey questionnaire. Most of the people who distrust Arisu without rational reason at the first question were selected different choices and significantly reduced in the second question. This proved that the ratio of distrust on the tap water is not actually the right reason and that by providing more choices, people's distrust on the tap water without rational reason can turn into more specific reasons.

Ion chromatography (IC) coupled with conductivity detector (CD) is a common system for the determination of perchlorate in water samples. Although the IC method with CD has been widely used for the determination of trace level perchlorate ion in water, sensitivity decreases dramatically as the complexity of the matrices increases. Here we proposed the application of ion chromatography coupled with mass spectrometry (IC-MS/MS) to significantly improve selectivity of perchlorate. The mean recovery of the method was 104.4 ${\pm}$ 5.7% and the relative standard deviation (RSD%) was 1.9 ${\pm}$ 1.3%. The alculated method detection limit (MDL) was 0.0207 ${\pm}$ 0.0099 ${\mu}g/L$. The concentrations of perchlorate were minimum <0.1 ${\mu}g/L$ and maximum 18.3 ${\mu}g/L$ in source water (Namhan, Bukhan and Han River). Hongreung showed higher concentrations ($1^{st}$-14.3 ${\mu}g/L$, $2^{st}$-18.3 ${\mu}g/L$) than the other places. And the concentrations of perchlorate were 0.18~0.34 ${\mu}g/L$ in the samples taken from the six water treatment plants and six intake stations in Seoul.
